SHOE-SUPPORT.

Specification of Letters Patent.

Original application filed September 9, 1910, Serial No. 581,171. Divided and this application filed February 19, 1915. Serial No. 9,393.

To all whom it may concern:

Be it known that we, ARTHUR E. JERRAM, J OSEPI-I GoULDBoURN, and ARTHUR BATES, subjects of the King of England, residing 'at Leicester, Leicestershire, England, have invented certain Improvements in Shoe-Supports, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the'drawings indicating like parts in the several figures.

The present invention relates to shoe supporting means for maintaining a shoe in place while it is being operated upon by tools of any description.

The invention is herein shown as embodied in the heeling machine of our application Serial No. 581,171 filed September 9, .1910 of which the present application is a division. In that machine the heel of the shoe is operated upon by drivers or awls but the invention is not limited in its application to this or to any particular type of machine.

In the usual course of shoe manufacturing there are presented to most shoe making machines shoes of various sizes, widths and styles and also right and left shoes of these different shapes. It is important that each I shoe, regardless of its shape, should be firmly held in place during the operation of the machine.

It is accordingly an object of the present invention to provide shoe clamping means capable of a wide range of adjustment but constructed and arranged, when the necessary adjustments have been made, to hold each shoe without the liability of displacement.

The features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawings, in which,--- 9 c Figure 1 is a plan view of the band clamp and its mounting, and Fig. 2 is a view in side elevation, partly in section, showing the clamping mechanism embodied in a heeling machine.

In Fig. 2 the present invention is shown as embodied in a heeling machine of the character disclosed in our co-pending application above identified. This machine has a frame 16 in which is mounted a plunger 8 carrying the jack 162 and also aplunger 6 carrying a gang of tools or drivers 10. The plunger 8 carries also a bracket 164. which carrier the shoe clamping elements. It will be understood that the shoe is placed on the jack 162 when the jack is swung outwardly. The jack is thereupon swung rearwardly, carrying the counter portion ofthe shoe into the band clamp 132 which acts to hold the shoe firmly in place during the subsequent operation of the machine. The bracket 164: and the elements carried thereby move up and down with the ack and shoe so that the relationship of these parts when once established is not disturbed until the finished shoe is taken ofi the jack. In the lower end of the bracket 164; is formed a vertical cylindrical socket for the reception of the shank 154: of the support 1 50. The end of the bracket 164 is split. and there is provided a clamping bolt 155 by which the shank 151 may be clamped rigidly in place but which aflords provision for a bodily angular adjustment ofthe support 150.

The support 150 has guidewavs on its lower face in which is received a sliding sec tion 140. On the upper surface of this section is formed a rack 151 which meshes with a pinion 152' on a cross shaft journaled in the support 150. At its outer end this shaft is provided with a hand not 153 by which the pinion 152 may be turned and the section 140 moved forwardly or rearwardly in the direction of the longitudinal axis of a shoe on the jack 162. The shaft of the hand nut 153 and the pinion 152 is bored to receive secured an eccentric clamping piece 157. When this is swung downwardly a shoulder on the hand nut 153 is forced against a stationary boss on the support 150, thereby a stationary pin to the outer end of which is Pivoted to the forward end of each lever 134 is a sleeve 183 and in-each of the sleeves is slidingly received a rod 144 pivoted at its inner end to an ear on the band clamp 132. Into the outer end of each sleeve 133 is threaded an adjusting screw 14?. which bears upon the outer end of the rod 144 and by which each rod may be forced inwardly. The band clamp 132 is of flexible material and has a constant tendency to expand and therefore forces the rods 144 into the sleeves against the'ends of the. screws 142. It will be apparent that the screws 142 afi'ord convenientmeans for independently adjusting the sides of the band clamp.

Each of the levers 134 at its inner end carries a threaded stud through which p'assesan adjusting screw 147 having a right and left thread and a knurled nut 148 at its outer end. By turning this screw the forward ends of the carrying levers 184 may be swung toward or from .eachother in asymmetrical manner and a corresponding adjustment of the band clamp effected. I

At the rear of the center of the band clamp 132 there is formed abo-ss from which projects a threaded rod 166. This .rod ,passes through .a bore in the yoke141 which is cut away to receive an adjusting nut 168. .By turning the nut 168 the rod 166 may be moved forwardly or rearwardly and theflposition of the rear portion of the bandclamp thus accordingly. adjusted.

From the foregoing description it will be seen that the band clamp has provision for the independent adjustmentof its sides and the backward and forward adjustment of itsrear portion in addition to provision for a symmetrical, widthwise adjustment of its side portions. reason of the various ad- .justments the contour of the band clamp may be made to fit a shoe of any shape or style. Having made these adjustments for a shoe of one size of such style, :shoes of different sizes and widths of the same style may be accommodated by merely turning nut .148 on the adjusting screw :147. In addition to'these adjustments which affect the band clamp directly there is provision for r the backward and forward adjustment-of the band clamp bodily without affecting the contour thereof and also a bodily angular adjustment of the'entire mechanism. This great flexibility of adjustment. adapts the supporting mechanism to receiveshoes varying in shape through a very wide range but when the proper adjustments have been made all of such shoes are firmly positioned upon the jack during the operatio-n of the machine.

Having I thus described our invention, what we claim as new and by Letters Patent is: r
